    introduction

    This cost-estimating and cost-management criteria document supports building constructionprograms within the Public Buildings Service (PBS) of the U.S. General Services Administration

    (GSA). This document presents the technical and administrative requirements for routine cost-

    estimating and cost-management tasks involved in a construction projects planning and execution

    stages, and defines cost-estimating practices and standards for professional services. This

    document replaces the previously issued GSA Handbook P 3440.5 and all associated versions.

    The instructions and criteria in this document are applicable to programming, design, construction-

    management, and other professional-services contracts that involve cost-estimating andcost-management tasks. The criteria for practices and documentation requirements apply to all

    professional services activities, whether provided through contract or by in-house GSA/PBS staff.

    The cost-estimating tasks addressed in this document must establish accurate project costs, ensure

    that they are based on programming requirements, keep costs within authorized limits, and collect

    GSA cost data to refine business practices and future cost estimates.

    Since project delivery methods affect how, and to some degree when, cost-management practices

    are applied, this document explains the basic requirements associated with each delivery method.

    This document has three major chapters:

    1 general requirements and principles

    This chapter presents the general estimating practices and standards required for all estimating

    services. It covers qualifications of estimators and estimating firms, principles of effective cost

    management, different types and formats of estimates, approaches to estimating, and the

    various cost-estimating and management tools available.

    2 prospectus project requirements

    This chapter defines the estimating service required for prospectus projects, including

    deliverables in the context of planning, design, and construction stages.

    3 delivery methods and deliverables

    This chapter explains when the deliverables defined in Chapter 2 must be provided for the

    following four delivery methods:

    Traditional (Design-Bid-Build)

    Design-Build Performance

    Design-Build (Bridging)

    Construction Manager as Constructor (CMc)

    Table 3 in this chapter shows the cost-estimating tasking requirements for the delivery methods

    by size and type of project.

    1general philosophyThe Federal Acquisition Regulation (FAR) 36.203 requires that every Government estimate be

    prepared as though the Government were competing for the award. Therefore, all costs that a

    prudent and experienced contractor would incur must be included in project cost estimates.

    A listing of known facts, construction tasks, and supplemental judgments form the basis of the

    estimate at each stage of design. This provides a realistic approach to estimating, and it creates a

    history of project cost development.

    P100, Facilities Standards for the Public Buildings Service, lists the estimating deliverablerequirements for each design phase, but they are clarified here.

    section 1.1

  • 7/29/2019 Building Services Project Estimation

    14/92

    estimator qualification and ethics

    1 requirements

    Capital project estimate submissions must be prepared by professional cost estimators

    unaffiliated with the design team or the Construction Manager as Contractor (CMc). Certification

    as a cost engineer by the Association for the Advancement of Cost Engineering (AACE), or as a

    certified professional estimator by the American Society of Professional Estimators (ASPE), is

    supporting evidence of an estimators qualifications, although it is not required.

    2 independent government estimate (IGE)The FAR requires that an IGE be prepared for all contracts exceeding $100,000. When life-cycle

    costing or other economic analyses are required to support a design decision, professional

    estimators must establish construction cost estimates for all options if any one of them is

    expected to have a first cost in excess of $100,000.

    The final cost estimate submitted for the 100% construction documents phase is used as the basis

    for the final IGE, which the contracting officer uses to determine whether an offerors proposedprice is fair and reasonable and reflects an understanding of the project requirements.

    A qualified Government employee whose major responsibility is creating or approving cost

    estimates for GSA must sign and approve the IGE, which serves as the basis for commitment of

    funds before the solicitation is issued

    3 ethics

    The standards of practice described in the Canons of Ethics published by the AACE and theASPE, and available on both their Web sites, apply to all estimating services.

    4 due diligence expectations

    GSA expects proper diligence in the preparation of estimates, which will grow steadily more

    accurate as the design progresses. While the estimator may need to make many assumptions

    in preparing the concept design estimate, once the construction documents phase has begun,

    2

    4project estimating requirements P-120

    section 1.2

  • 7/29/2019 Building Services Project Estimation

    15/92

    1estimates will no longer contain major assumptions. The project team will designate one

    person to compare successive project estimates and prepare an orderly and comprehensive

    reconciliation.

    The architect-engineer (A-E) must work closely with GSAs independent estimator to coordinate

    the estimates with design submissions and the scope of work, to review assumptions

    concerning exclusions and inclusions, and generally to ensure that the estimate reflects GSAs

    intent. These estimators must have a thorough understanding of the marketplace in which the

    project is located, research market prices, and obtain price quotes for specialty items.

    5 penaltiesGSA contractors are advised to be aware of 18 United States Code 1001, which deals with the

    False Statements Act. This code states, in part:

    whoever, in any matter within the jurisdiction of the executive, legislative, or judicial

    branch of the Government of the United States, knowingly and willfully -

    (1) falsifies, conceals, or covers up by any trick, scheme, or device a material fact;

    (2) makes any materially false, fictitious, or fraudulent statement or representation; or

    (3) makes or uses any false writing or document knowing the same to contain any materially

    false, fictitious, or fraudulent statement or entry;

    shall be fined under this title, imprisoned not more than 5 years or, if the offense involves

    international or domestic terrorism (as defined in section 2331), imprisoned not more than

    8 years, or both.

    cost estimating and management

    practices1 cost management principles

    design within budget

    Unless otherwise specified in design-contract documents, the A-E must design the project

    so that construction costs will not exceed the funding limitations established as the Basis

    of Fee Negotiation. FAR 36.609-1 requires that the A-E redesign the project at the firmsown expense to ensure that a responsive construction bid amount will be within funding

    limitations.

    prospectus authorization/appropriation

    In accordance with the Public Buildings Act of 1959 (PL 86-249), as amended, the United

    States Congress must authorize the scope and budget of each major capital construction

    project before design begins. Once Congress has approved a projects construction

    budget, it cannot be increased, so the design team must approach prospectus funding asan absolute limit.

    pursuit of construction services

    Construction bids may be solicited only if the Estimated Cost of Construction at Award

    (ECCA) amount at final construction documents is within congressionally authorized

    prospectus limits.

    itemized cost management

    When project funds are secured from different agencies or are provided as a dedicated

    allowance for a specific program goal, independent estimates must be made for each,

    allowing separate tracking of expenditures. Funding allocated for such projects is tracked

    to confirm that expenditures are apportioned according to amounts authorized by each

    agency, so as not to exceed the dedicated allowance.

    independent estimates

    The Government requires third-party estimators for major construction projects to verify

    3

    6project estimating requirements P-120

    section 1.3

  • 7/29/2019 Building Services Project Estimation

    17/92

    1that the projects scope and cost are within budget. These estimates are prepared by an

    independent cost estimator who is not affiliated with the design firm or the Construction

    Manager as Contractor (CMc). The design team provides all required documentation forthe estimator to provide estimates for, at a minimum, the following phases:

    Final Concept Design

    Final Design Development

    90% Construction Documents

    100% Construction Documents

    2 estimating formatsUsing standard estimating formats for cost estimating and cost management:

    Ensures a uniform cost-control framework throughout the various stages of project

    development.

    Defines a proper level of detail to set expectations for the estimating effort.

    Serves as a checklist to ensure complete coverage of project scope.

    Provides for a standardized historical database or library.

    space type estimates

    This format, used primarily for new construction projects, applies space-type unit costs to

    planned space needs, resulting in a set of space-related construction costs. These costs

    may be adjusted by adding known costs for special requirements defined through other

    estimating formats. The sum of space-type costs and special-requirement costs equals an

    Estimated Construction Cost (ECC) for the project.

    Since GSAs General Construction Cost Review Guide (GCCRG) uses space-type estimates,cost estimators must be familiar with this technique (see Chapter 1, Section 4.4 for an

    explanation of GCCRG).

    uniformat estimates

    Uniformat estimating applies unit-cost data to building-system and component site elements.

    This systems approach uses a hierarchical structure of cost elements, beginning at Level

    1 with basic systems, such as Substructure, Exterior Enclosure, and Interior Construction,

    7general requirements and principles

    section 1.3

  • 7/29/2019 Building Services Project Estimation

    18/92

    and proceeding to successively more detailed subdivisions of these systems at Levels 2-5.

    The resulting levels of detail not only serve to structure cost information but also facilitate

    estimates to whatever level of detail the design team can provide as the project is developedthrough the design submission phases. For example, by the final concept design phase,

    the design team and estimator may have Level 4 information on Substructure, but only

    Level 2 detail for Interior Construction.

    Although the construction industry uses several variations on the Uniformat concept,

    GSA requires that cost estimators use its particular version, for consistency in use and

    maintenance of GSAs cost databases. GSAs Uniformat estimating format is illustrated in

    Appendix A: Estimating Formats.masterformat estimates

    MasterFormat, a product of the Construction Specifications Institute (CSI), is the most

    widely used standard for organizing building-project specifications and detailed cost-

    estimating data in the U.S. It is used particularly when drawings and specifications are

    sufficiently detailed to allow material and equipment quantity takeoffs, and it is typically

    aligned with a general contractors approach to preparing a bid. Visit the Construction

    Specifications Institute Web site (www.csinet.org) for more information.work-item estimates

    GSA Repair and Alterations (R&A) projects tend to utilize scope descriptions and cost

    estimates organized by work items. While work items may vary significantly depending on

    the nature of the project, as defined by GSA program offices and client requirements, the

    following list reflects a typical, but not comprehensive, work-item classification for R&A

    projects:

    Building exterior Electrical Building interior Life safety

    Accessibility Elevators

    Structural Hazardous materials abatement

    Mechanical Roofing

    Plumbing Security

    8project estimating requirements

    section 1.3

  • 7/29/2019 Building Services Project Estimation

    19/92

    1Traditionally, R&A projects have used the work-item basis because it allows the removal

    or addition of project scope to meet budgetary limitations and allowances. GSA assigns

    alphabetical codes to the work items when describing the project and its costs for each R&Aprospectus, as required by the Office of Management and Budget (OMB) and Congress.

    See Chapter 2 for further description of non-prospectus projects.

    other formats

    GSA may require that estimates be formatted in additional ways. For instance, it may be

    necessary to subdivide estimates for individual buildings and other components into new

    construction and major renovation.

    Work items on non-prospectus projects frequently evolve from Building Evaluation Reports

    (BERs), and estimates for these projects may follow a Work Breakdown Structure (WBS).

    Situations that might require a WBS include:

    Differing financial commitments of multiple tenants of a project, requiring separate

    contracts for each tenants work.

    The need for separate contracts for buildings and their site work, such as at border

    stations.

    Phased renovation projects requiring swing space for a variety of tenants ordepartments.

    Projects to be funded over more than one year.

    Separation of a project into base-contract work and options or alternates.

    Projects below $100,000 may be executed under line-item or job-order contracts, for which

    cost estimates are derived from line-item databases. Cost proposals for the services of the

    A-Es estimator and the independent government estimator must be submitted to GSA on

    Form 2630/2631, shown in Appendix E.

    1estimating requirements

    1 general

    The Government requires cost estimates for, at a minimum, the following phases of design

    Establishing an initial project baseline.

    Preliminary concept design, with multiple schemes of design

    Final concept design preceding value engineering

    Final concept design Design development preceding value engineering

    Final design development

    75% construction documents

    90% construction documents

    100% construction documents

    The estimate must include all elements of the proposed project work (including all design-contract modifications), regardless of the design phase. The estimate must all include

    verification and continuity of cost budgets in the transfer from estimate to the contractors

    schedule of values. Where costs are included for details not indicated on the drawings and

    specifications, the independent government estimator must include design assumptions to

    complete the scope. The estimator must check all cost-estimate calculations for accuracy and

    completeness, including assessing whether estimates completely and accurately represent

    design features and quantities.

    Lump-sum pricing is not acceptable without description and quantification.

    2 warm-lit shell vs. tenant-improvement (TI) cost estimates

    GSAs pricing policy calls for a separate tenant-improvement breakdown of all tenant-space

    fitout, identified by agency. You can find GSAs pricing policy and the related modifications and

    clarifications at the following external Web site: http://www.gsa.gov/rentpricingpolicy

    Security upgrades

    3 contents and degree of detail

    Table 1 illustrates the formats and minimum level of detail required for cost estimates at each

    design phase.

    unit pricing

    Unit-price cost estimates are based on detailed design documents and developed by

    adding up the direct costs of materials and supplies, labor, and construction equipment

    for each individual task of construction work. The basis for these unit costs must be well

    documented and included in the supporting data of the estimate. To these direct costs are

    added applicable indirect costs, such as overhead and profit at a subcontractor level, to

    reflect the in-place construction cost per unit of work required.

    For concept design estimates, it is acceptable to use unit prices combining labor, materials,

    and equipment costs in a single figure. For estimates prepared at the design development

    and construction documents phases, GSA requires separate labor, material, and equipment

    unit pricing.

    Items that are a significant percentage of the total projects cost require the greatest

    estimating effort. For such items, indirect costs and other markups associated with eachtask or work item must be separately identified and considered. On a project-by-project

    basis GSA requires quotes from suppliers or specialty contractors to document the costs of

    such major items, and the estimator must be prepared to discuss them with GSA.

    Documentation of unit-price data for smaller items could include price quotes, audits,

    catalog cuts, and historical costs to clarify price bases and assumptions made when other

    information is not available. The independent government estimator provides a general

    12project estimating requirements P-120

    1statement describing the sources of unit costs and quantities used for each cost division or

    category, but individual source references for each itemized cost element are not required.

    general conditions and profit

    Feasibility Studies, Program Development Studies, and Concept Design

    A percentage allowancean overall percentage allowance for the General Contractors

    general conditions, bonds, insurance, and corporate overhead and profitis appropriate

    if the project involves no unusual coordination, site preparation, or specialized support

    services.

    Design Development and Construction Documents

    It is appropriate to estimate these costs with two breakdowns:

    General Conditions: Comprised of itemized general requirements and job-site

    supervision.

    Mark-Ups: Comprised of general and administrative costs (including state and

    local taxes), profit, bonds, and insurance.

    site and design contingencies

    Contingencies are an integral part of the total estimated costs of a project and cover

    costs that may result from incomplete design, unforeseen and unpredictable conditions,

    or uncertainties concerning project scope. The amount of the contingency will depend

    on the status of design, procurement, and construction, as well as the complexity and

    uncertainties of the component parts of the project. Contingency is not to be used to avoid

    making an accurate assessment of expected cost. GSA may choose to set aside separate

    contingencies for major schedule changes, unknown design factors, unanticipated

    regulatory standards or changes, additions to project scope, force majeure situations, or

    congressional budget cuts.

    Contingencies must always be separately identified so that the magnitude of a contin-

    gencys impact is clear. For example, the Independent Government Estimator may never

    add contingency by concealing it within unit pricing or quantity estimates or takeoffs.

    Site and design contingencies start at 10% during the programming and planning stages

    and are reduced to zero as the design develops (seeTable 2).

    1escalation

    Escalation is the anticipated increase in the projects Escalation is the anticipated increase

    in the projects cost due to inflation between the time the estimate is prepared and when theproject is finished, since inflation continues during project construction. For simplicity, the

    estimator must assume that half of the work will occur before the midpoint of construction

    and half after. Therefore, the estimate is escalated to the midpoint of construction to reflect

    the contractors provision for inflation in its bid.

    In the planning stage, escalation rates are taken from the GCCRG. As the design progresses,

    the A-E and GSA must agree on an annual construction-cost escalation compounding rate,

    based on a market survey prepared by the A-E, for use in all design estimates and cost

    analyses. It is the responsibility of the design A-E to control the cost of the project so thatwhen the ECCA budget is reduced by the forecasted escalation rate, the residual budget

    amount equals the current value of the project.

    art-in-architecture

    The art-in-architecture set aside amount is 0.5% of ECCA.

    construction contingency

    The construction contingency is an allowance for cost growth that may occur during

    construction as a result of unexpected circumstances or incomplete design documents.

    GSA currently recommends 7% for new construction projects and 10% for renovations, but

    may direct the use of different figures on a project-by-project basis.

    applying markups, contingency and escalation

    Figure 1 demonstrates how mark-ups, contingencies, and escalation should be calculated

    and applied to projects.

    reviewing and reconciling estimatesOn projects for which GSA requires the preparation of an IGE, the A-E is responsible for

    designating a member of its team to reconcile the IGE with its own estimate in an orderly and

    comprehensive manner.

    cost-management requirements

    Accurate estimating is an important component of GSAs cost-management process, as

    well as an important decision-making tool for the design team in its selection of systems

    15general requirements and principles

    section 1.4

  • 7/29/2019 Building Services Project Estimation

    26/92

    and materials. In order to serve these purposes, careful consideration must be given to the

    following:

    Cost-element comparisons Prepared at each milestone to compare the currentestimate to the previous milestone estimate and to the overall budget and to the

    baseline estimate to ascertain whether design or scope changes have been made

    or need to be made. Refer to the estimate tracking sheets in Appendix B.

    Earned-value accounting Used in conjunction with cost-element comparisons,

    the earned-value process allocates cost as it is committed, or as a part of the project

    is completed. Decisions regarding contingency and escalation are important in this

    process. For additional information, see the Whole Building Design Guide web site

    at www.wbdg.org.

    Life-cycle cost analysis Used to evaluate the implications of decisions made

    during the design process not only on initial cost but also on life-cycle costs. Issues

    considered typically include energy utilization, sustainability, maintenance, and

    operations. See Chapter 2, Section 2.2 for details.

    Shell and core, security upgrades, and tenant improvement (fitout) GSA

    requires subdividing the estimate into costs for the shell and core and tenant

    improvements, including the associated professional services costs included in the

    occupancy agreement between tenants and GSA. Both the A-Es estimator and the

    independent government estimator must submit their cost proposals for professionalservices to GSA using Forms 2630 and 2631. See Appendix E for sample forms.

    Phasing/scheduling packages Used for project work divided into more than one

    construction phase. Separate cost estimates, accompanied by an overall project

    ECCA summary, support each phase. For phased new construction, a construction

    management (CM) firm hired by GSA must prepare a post-award construction

    cost analysis for each phase. After contract award of the last construction phase,

    a combined post-award construction analysis for the composite project bid is

    prepared.

    Multistructure projects Projects involving more than one structure require

    separate estimates for each structure. Separate site construction-cost estimates

    must be associated with the estimates for each structure involved. A CM firm hired

    by GSA must prepare a construction-cost analyses for each structure and site

    development after the multistructure project is awarded.

    Bid alternates and options A CM firm hired by GSA must prepare separate cost

    estimates for the base bid and for each individual alternate or option when the

    project requires them.

    GSA developed the General Construction Cost Review Guide (GCCRG) to assist estimating in

    the planning phase of new construction projects. Figure 2 is an example of a GCCRG estimate.

    Project Cost Estimate (PCE)

    The PCE was designed for programming and pre-design estimates. Applications may

    include BERs, feasibility and program development studies, site acquisition and Market

    Survey studies, and design. Figure 3 is an example of a PCE tool summary, Figure 4 is an

    excerpt of a more detailed estimate sheet.

    See Chapter 2, Section 2.2 for details.

    cost-estimating systems

    GSA encourages but does not require the use of computer-based cost-estimating programs

    to mitigate manual calculation errors and facilitate changes. The requirements defined

    in this document can be easily met by using various commercially available computer

    software programs and spreadsheets. Generic spreadsheets allow user adaptation and

    offer flexibility in applying different cost databases.

    Figure 5 is an excerpt from a Uniformat-structured estimate report from a cost-estimatingsystem used at the design development phase. It illustrates the requirement to break down

    unit prices into labor, materials, and equipment. The report uses the Uniformat levels to

    organize the estimate and define the detail of the unit price items.

    Figure 6 is an excerpt from a MasterFormat-structured estimate report developed at the

    design development phase. It illustrates the requirement to break down unit prices into

    labor, materials, and equipment.

    project requirementsThis chapter deals with GSAs requirements for cost estimating during the design and construction

    phases of a project. It defines and describes the scope and level of detail required for each potential

    deliverable and product required, in the context of each phase of the project. For information on

    the feasibility study and program development study (PDS) phases of a capital project, see GSAs

    Project Planning Guide, available in PDF format at www.gsa.gov, which is briefly described below.

    1 project planning guide

    GSA developed the Project Planning Guide to assist participants in the Capital Program

    development process in evaluating, developing, and implementing Federal facilities projects.

    The guide outlines the project delivery process and offers some keys to success.

    The guide is divided into five sections and several appendices:

    Overview of GSAs Capital Program Outlines GSAs basic capital program

    development-planning process and the fundamental roles of the feasibility study andthe program development study.

    Whats Important and When Discusses GSAs primary business and program goals

    as presented in the feasibility study and the PDS.

    Pre-Planning Phase Describes the role played by GSAs daily management of facility

    requirements, customer needs, and portfolio planning in the project development

    process.

    Feasibility Study Phase Outlines the process for beginning, conducting, andcompleting a feasibility study, a process that ends with the submission of the

    prospectus package for site and design funding. This section describes the process,

    deliverables, and keys to successful development of a sound project and site/design-

    funding request.

    Program Development Study (PDS) Phase Outlines the process for evaluating

    the feasibility study as the foundation for the PDS, digesting new information, refining

    the project, and directing the projects design and construction strategy. This section

    2design and construction phase cost

    estimating1 basic concept: for all phases

    Any design-submission deliverables may include, but are not limited to:

    cost estimates and reports

    market survey

    cost growth reports

    space-type cost analysis

    life-cycle cost analysis

    value engineering studies

    independent estimate reviews

    budget analysis

    construction award bid analysis

    database information preparation

    construction modifications & claims analysis

    value engineering change proposals analysis (VECPS)

    risk analysis reports

    The purpose is to establish a cost management system that tracks budgets established based

    on the prospectus in a Uniformat Level II, comparing cost growth and cost modificationsfor all Uniformat Level II elements through design, procurement, construction and project

    completion.

    As a general rule, early in the process Uniformat is the primary estimate format, although CSI

    MasterFormat may be selected on a project-by-project basis. GSA usually requires work items

    on major renovation projects or when the project is to be separated into major components or

    subbuildings. The space-type summary is usually required at various project phases. A Cost

    Growth Report is required at all submissions, and a Life-Cycle Cost Analysis is required through

    design development and potentially during construction documents phases for significant

    items.

    An independent party hired by GSA conducts a value engineering (VE) workshop, and VE is

    provided in accordance with the design submissions requirements of P100. GSA may elect to

    conduct an additional VE study at the construction documents phase on a project-by-project

    basis.

    When GSA completes an internal review of the estimate, or reconciles an independent estimate,

    and at the conclusion of the VE study, a final estimate is submitted.

    2 cost estimates and summaries

    summary of format requirements

    Table 1 in Chapter 1 displays the type of estimate to be prepared at the various design stages.

    preliminary concepts

    Pre-concept estimating generally requires the preparation of estimates on three competing

    basic schemes/concepts, allowing GSA to select its preferred scheme.

    For each scheme, the A-Es estimator prepares separate estimates for phased work,

    multistructures, and or bid alternates/options. The A-E also submits estimates for concept

    design analyses/studies as specified in design-programming directives and/or design-

    criteria references, and a comparison sheet for multiple concepts/schemes.

    concept design

    These estimating requirements apply to any concept-level submission. If a projects design

    requires multiple concept submissions, each concept submission must be supported bythe estimates described here.

    Estimators must calculate quantities for appropriate systems or apply parameters to

    appropriate building areas. Applied unit costs may be based on combined material and

    labor costs. Concept estimates must match the estimate format of the budget estimate

    to facilitate cost-breakdown comparisons. For prospectus work, this typically requires that

    Uniformat Level 3 estimates be prepared, delineating cost-element categories shown in

    30project estimating requirements P-120

    section 2.2

    2Appendix A.1: Uniformat Level 1-5 Cost Elements. However, certain projects (such as nonpro-

    spectus repair and alteration work) may have had their budgetary estimates done in work

    items or CSI MasterFormat.

    Backup worksheets must support detailed estimates, covering all cost-sensitive project

    data and defining all major assumptions made. Backup estimating data and quantity-

    survey information may be in any format, grouped under appropriate format classification

    headings.

    The A-E is required to provide the Independent Government Estimator advance copies of

    all concept plans and documentation early enough to allow for the preparation of required

    estimates as part of the concept design submission. Advance documents must include

    floor plans, elevations, sections, and perspective views in sufficient detail to allow a realistic

    parametric cost assessment. In addition, the A-E provides:

    A statement on the conceptual approach and general features for each major

    building system, including an itemized listing of anticipated types and approximate

    capacities/sizes. Block loads for structural, mechanical, and electrical systems.

    Quality levels of major materials and systems to be used, including any special

    design programming or code requirements relating to fire protection, HVAC,

    plumbing, electrical, and structural components. A copy of the design program to ensure that the estimator understands goals,

    objectives, and design directives that may not yet be reflected in concept design

    submission documents.

    To ensure that the project is developing on-budget, the A-Es estimator must also submit a

    list of cost-saving items that collectively would reduce the projects cost to approximately

    10 percent below budget.

    The Independent Government Estimator is required to prepare an ECCA summary sheet to

    Uniformat Level 2, representing all project and estimate data. Each ECCA summary must

    compare the design cost breakdown with any budget cost values escalated to the midpoint of

    construction, including per-square-meter or square-foot calculations of overall project cost.

    design development

    To support design development estimating, the A-E provides the Independent Government

    Estimator the documentation necessary to describe proposed types, quality, and quantities

    31prospectus product / deliverable P-120

    section 2.2

  • 7/29/2019 Building Services Project Estimation

    42/92

    of building features, systems, equipment, and materials. Project scheduling must allow for

    the early delivery of advance copies so that the required estimates can be included with the

    design development submissions.

    As a separate cost-saving task, the A-Es estimator must also submit a list of cost-saving

    items that collectively would reduce the projects cost to at least 10 percent below budget.

    The independent government estimator prepares an ECCA estimate for the base bid and

    separate estimates for phased work, multistructures, and/or bid alternates or options. An overall

    project ECCA estimate will also be prepared, incorporating all project segments, for analyses

    or studies specified in design-programming directives and design-criteria references.

    Backup worksheets are required to support the detailed estimates, which represent allcost-sensitive project data and define all major assumptions. Backup estimating data and

    quantity-survey information may be in any format, but must be grouped under appropriate

    format classification headings. The Estimate Tracking Sheet and Elemental Cost Summary

    forms must be submitted, including per-square-meter or square-foot calculations.

    construction documents

    Estimating requirements given here apply to all required construction documents

    submissions75%, 90%, and 100% CDsunless specified as applicable only to finalconstruction documents.

    If the overall projects construction documents estimate exceeds the budget, the A-E is

    again required to propose cost-saving measures to bring the project within budget, at its

    own expense. To avoid over-budget construction bids, the A-Es estimator must identify at

    least five construction cost-saving items, formulated as bid alternates, to bring the projects

    estimate at least 10 percent below budget.

    The Independent Government Estimator prepares an ECCA estimate for the base bid,including separate estimates for phased work, multistructures, and/or bid alternates or

    options with any addenda. An overall project ECCA estimate is also prepared, incorpo-

    rating all project segments, for analyses or studies, as specified in design-programming

    directives and design-criteria references.

    ECCA estimates are developed using MasterFormat, with detailed material and labor

    breakdown and appropriate subdivisions as shown in Appendix A. MasterFormat estimates

    2are also summarized in Uniformat Level 3 estimates and work items. For both formats,

    backup worksheet estimates are arranged by cost categories, with a summary sheet

    combining all category costs. The 90% and 100% Construction Document estimates are

    prepared at the same level as required for the contractor performing the construction work,

    in accordance with the FAR.

    Backup worksheets are required to support the detailed estimates, which represent all

    cost-sensitive project data and define all major assumptions. Backup estimating data and

    quantity-survey information may be in any format, but must be grouped under appropriate

    format classification headings.

    Submissions must follow the formats in Appendix A and provide per-square-meter or

    square-foot calculations.

    MasterFormat cost estimates are prepared to an equivalent of Uniformat Level 5, with unit

    prices separately representing material and labor. Cost-element lump-sum estimating for

    either format system may be used only by permission of GSA. If cost elements are transferred

    from previous submission levels, quantity values must be verified and unit costs adjusted to

    reflect escalation to the construction documents submission date. Allowances for design

    contingencies, general conditions and profit, bonds, and construction escalation are added

    to calculate the ECCA amount.

    3 market survey

    GSA requires that the design A-E prepare a Market Survey for every project and for each

    submission indicated in the Tasking Matrix (Table 3 in Chapter 3), and described below.

    A Market Survey explores all factors influencing construction costs relevant to the current

    stage of design. The Market Survey preparer gathers pertinent data by interviewing local firmshaving knowledge of construction in the area. Possible sources include, but are not limited

    to, general contractors and subcontractors, builders associations, local government officials,

    architectural and engineering firms, builders-exchange and construction-reporting firms, and

    bankers and commercial mortgage firms. Particular emphasis must be placed on ascertaining

    the availability of mechanical and electrical subcontractors and the associated skilled labor

    trades. The Market Survey must reflect recent and expected bidding conditions that may

    influence the cost of construction and list all sources of data.

    33prospectus product / deliverable P-120

    section 2.2

  • 7/29/2019 Building Services Project Estimation

    44/92

    The person who prepares the Market Survey visits the site and local market areas to determine

    the following:

    Availability and shipping origin of major project materials. Capability of local fabricators, precast yards, concrete plants, etc.

    Availability of labor crafts necessary for the project, especially skilled labor.

    Availability of special erection equipment.

    Anticipated capacity of local contractors during bidding period.

    Special conditions that might influence bidding.

    Local escalation experience.

    Site accessibility.

    Batch plant options for concrete and asphalt.

    Applicable local taxes or gross receipts taxes where the project will be constructed.

    Costs of remoteness, such as labor for lost time, housing allowance, or requirement for

    onsite housing or material delivery costs.

    The Market Survey also includes:

    Who was contacted (person, firm, phone, e-mail).

    Where they are located.

    When contact was made.

    Why they were contacted.

    What information was obtained.

    A summary assessment with specific recommendations.

    concept design

    The A-E conducts a Market Survey as described above and as required by the Tasking

    Matrix (Table 3 in Chapter 3).

    design development

    During the design development phase, the concept design phase Market Survey is

    updated, verified, and refined to include all changes necessary to reflect new information

    34project estimating requirements P-120

    section 2.2

    2

  • 7/29/2019 Building Services Project Estimation

    45/92

    2on local market conditions, such as regional building booms and other potential major

    projects with comparable construction schedules. These updated Market Surveys are

    submitted as required by the Tasking Matrix (Table 3 in Chapter 3).

    construction documents

    At the 90% and 100% construction documents phases, the survey process intensifies, and all

    data gathered is reported. The report clearly depicts the likely bidding market, other projects

    likely to be on the market, and how hungry the market is likely to be at the scheduled time

    of bid. The final estimate must incorporate the surveys conclusions and reflect the current

    bidding climate, including information on the expected number of bidders for general and

    subcontractors, the amount of competition among contractors, and other conditions that

    may have an impact on the construction project.

    Note that in this phase the projects construction manager as agent will be promoting the

    project within the construction industry to develop interest for good competition.

    4 cost growth report

    GSA uses the Cost Growth Report (CGR) to track cost growth at each design phase by

    comparison with the project budget. This is done by comparing the prior submissions Uniformat

    Level 2 costs for each cost element with the current submissions Level 2 costs, and identifying

    the cause of large variances. The A-Es estimator prepares this report for each design-phase

    submission, using GSA Form 3474, Project Cost Comparison Summary. See Appendix B: Estimate

    Tracking Sheets for a sample of the form.

    preliminary concept design

    Each design concept considered during this submission must be within the projects overall

    construction budget. The A-E will be required to redesign any concept design scheme not

    within the budget to bring it within budget constraints at its own expense.

    For each concept scheme, the A-Es estimator lists cost-saving ideas that collectively will

    bring project costs within budget. The Independent Government Estimator validates these

    cost-saving measures by preparing an order of magnitude estimate of savings for each of the

    A-Es proposed measures. The A-E submits its Cost Growth Report on GSA Form 3474.

    final concept design, design development, and construction documents

    If the estimates for the concept design and design development submissions exceed the

    project budget, the A-E is required, at its own expense, to propose cost-saving measures

    to bring the project within budget. Just as described above for the preliminary concept

    designs CGR, the A-E summarizes the final concept design estimate on GSA Form 3474

    and compares it to the project budget. This report is supported with cost estimates for each

    proposed cost-saving item. The independent government estimator validates these cost-

    saving measures as outlined in the paragraph above for the preliminary concept design

    phase.

    If the estimate for 90% construction documents exceeds the project budget, the A-E is

    required to propose cost reductions in the form of bid alternates sufficient to ensure receipt

    of bids within budget on the scheduled bid date. The Independent Government Estimator

    validates these cost-saving measures, as indicated in the paragraph above, for the concept

    design and design development submissions.

    25 space-type cost analysis

    As part of a new construction-project cost-estimate submission, the Independent Government

    Estimator estimates construction costs by space types by:

    Identifying all project space types, considering at least those categories listed in the

    GCCRG.

    Separately itemizing special costs outside normal requirements of listed space types,

    addressing at least those listed in the Appendix as Special Costs Excluded.

    6 life-cycle cost analysis

    Life-cycle costing (LCC) is the development of all significant costs of acquiring, owning, and

    using an item, system, or service over a specified length of time. The time period used is the

    projected effective useful life of the facility, and its determination includes consideration of

    functional obsolescence of major components or systems. It is used to compare and evaluate

    the total costs of competing solutions based on the anticipated life of the facility or product to

    be acquired.

    The value of an item includes not only consideration of the costs of acquiring it, but also the

    costs of using it or the cost of performance for as long as the user needs it. Costs of repairs,

    operations, preventive maintenance, logistic support utilities, depreciation, and replacement,

    in addition to capital cost, all contribute to the total cost of a product to a user.

    For further guidance refer to Facilities Standards for the Public Buildings Service (PBS P100)

    and GSA Value Engineering Guide (PBS-PQ250 and 251).

    7 value engineering studies

    Value engineering (VE) is conducted during the concept design and design development phases

    to explore cost saving/value-enhancing options before selecting final design features. GSA may

    conduct additional studies during the 75% and 90% construction documents phases, and for

    100% construction documents if deemed necessary due to technical or budgetary constraints.

    A single study may be appropriate on smaller, less complex projects. The basic approach is to

    consider macro level issues at concept design and more micro level issues at design development.

    In general, decisions made as a result of the first study will not be reconsidered in the second

    study unless significant new information is available. Furthermore, design changes implemented

    as a result of the studies will generally be considered within the bounds of the normal design

    process. Exceptions to this will be considered on a case-by-case basis.

    baseline prospectus

    Translate the approved prospectus line items into Uniformat Level II to be used as a basis

    of comparison and control throughout the project lifecycle.

    design concept

    For major capital construction and certain other projects, a VE study will be included as a

    requirement for the concept design submissions. GSA contracts with the VE consultantdirectly, rather than through the A-E, but the A-E participates in and reviews VE proposals

    to address project feasibility and adherence to design programming requirements. The

    A-Es cost estimator must be available to answer the VE consultants questions concerning

    the origin of A-E concept design estimate unit costs and interpretation of work-element

    descriptions. Once GSA determines what VE consultants recommendations are to be

    used, the design A-E must incorporate these recommendations into design documents as

    part of the scope of work.

    For new construction projects, the first study at concept design is intended to review basic

    design decisions that pertain to areas such as:

    Siting and building orientation

    Building form, shape, and massing

    Layout

    Proportion of occupiable area to gross area

    Design criteria Building systems selection options

    Space program options

    Building space/volume parameters

    Vertical and horizontal circulation

    Major mechanical-electrical-plumbing (MEP) considerations

    Overall energy considerations

    Specification and performance requirements

    Proposed design details Layout options within overall building geometry

    Specific MEP system selections

    Site paving, grading, and utilities

    Phasing and scheduling plans

    Major constructability issues

    The A-E must incorporate the VE consultants recommendations approved by GSA into the

    design as part of the scope of work.

    8 budget analysis

    An ECCA summary is prepared at each milestone, using the formats in Appendix B, to compare

    the current design-cost breakdown with the previous submissions costs or the budget, with all

    values escalated to the current submission date. The summary must include allowances for

    design contingencies, general conditions and profit, and construction escalation and yield an

    overall project cost per square meter or square foot.

    9 requirements for bid submission

    Procurement officials ensure that the bid packages include a lump-sum bid requirement for

    each bid option, alternate, and unit-pricing item.

    costs submitted as the payment schedule for monthly progress payments for each trade or

    subcontract.

    The Independent Government Estimator reviews the final cost estimate in Uniformat Level

    3 and revises it to align with the actual bid price. The adjusted cost data is provided to GSA

    in formats found in Appendices C and D.

    After completion of the above cost analysis, the estimator uses a format similar to that

    found in Appendix D to provide a synopsis of the project space plan, efficiency, scope, and

    basic design parameter measures.

    GSA will provide the A-E and the Independent Government Estimator the following data:

    The abstract of bids received for the procurement with an indication of the award

    amount and the bids offered by all contractors.

    Any breakdown or verification of contractor or subcontractor prices in the course

    of contract award.

    The contracts approved schedule of prices to be used for progress payments.

    11 cost database

    GSA uses cost data collected for similar building types to develop space-type cost benchmark

    tools to improve budget development for future projects. Therefore, GSAs regional project

    manager provides cost estimates, reconciled estimates, bid analysis, and construction cost

    reconciling back to the bid estimate to the regional cost advocate or Central Office cost-management staff to compile this data into GSAs cost database.

    12 construction modifications and claims analysis

    This section provides information, procedures, and guidance for estimating and processing

    construction contract modifications. Contract modifications include change orders, contractor

    section 2.2

    52/92

    claims, formal resolution of constructive changes, the impact on unchanged work, suspension

    of work, and time extension.

    An independent estimate for contract modifications requested by the Government must beprepared before the proposal request is sent to the contractor. The Independent Government

    Estimator must be provided the same documents concerning the proposed modification that

    the contractor will be provided, or have access to them.

    The IGE prepared in response to a contractor-initiated proposal must be prepared to the same

    level of detail as the contractors proposal and be based on the scope of the modification. A

    copy of the contractors proposal with the costs deleted can be used.

    Regulations require an IGE for any procurement of $ 25,000 or more. If the Contracting Officerdetermines it is necessary, he or she may require estimates of lesser amounts. In the case of

    contract modifications, the $25,000 trigger figure is the sum of the absolute values of decreases

    and increases. For example, a modification resulting in decreases of $10,000 and increases of

    $16,000 would sum to the absolute value of $26,000, and an IGE would be required. Adjustments

    in methods or formats for the prime purpose of escaping this requirement are prohibited.

    For all negotiated procurements, including contract modifications, regulations state that award

    must not be made unless:

    The final IGE equals or exceeds the negotiated price, or

    In the case of reductions, which must be considered separately from increases, the

    negotiated credit is equal to or exceeds the final IGE, and

    The correct final IGE is included in the contract file, supplemented by a complete

    statement justifying the award at a cost different from the estimate, and adequate for

    subsequent review.

    The overall objective of a contract modification negotiation is to reach an agreement with the

    contractor that is in the best interest of the Government. The lowest possible price does not

    always meet this objective nor would a generous price, if that price offers more payment than

    necessary to include sufficient incentive. The negotiation team strives for some intermediate

    point, which is generally regarded as the lowest reasonable price the amount at the bottom of

    the price range that the negotiator considers to be fair and reasonable.

    53/92

    To arrive at this price the negotiator must at least partially rely upon an IGE based on a

    detailed analysis of the change in requirements and existing job conditions. For the most part,

    the estimate must be similar to, and take into account, those same conditions and elements

    occurring in the contract, as each applies to the change order scope. In lieu of better data, the

    IGE for bid evaluation may be used for assistance. The Independent Government Estimator

    must understand the scope of the change and prepare an accurate quantity takeoff for each

    direct item of change, using labor, material, and equipment costs and sequentially applying

    appropriate overhead, profit, and bond costs. Since this formal, approved IGE is used to evaluate

    the reasonableness of the contractors proposal, it must be prepared on a comparable and

    realistic basis by an estimator familiar with the modification and claim processes. The estimator

    must review the costs presented in the contractors proposal for accuracy, reasonableness, and

    allowableness. Of those costs found allowable (see FAR 31.2), each must be further reviewed

    for applicability to the requested modification.

    The Independent Government Estimator must:

  • 7/29/2019 Building Services Project Estimation

    54/92

    The Independent Government Estimator must:

    Review the change documents and become familiar with the requirements of the

    changed work.

    Determine the status of construction and how the changed work will fit into the

    construction schedule.

    Use methods, capabilities, and labor rates matching those of the contractor performing

    the work.

    Price each item at rates in effect at the time the changed work will be done.

    Attempt to agree with the contractor on scope and estimate structure before preparing

    the IGE.

    Unless otherwise agreed, use MasterFormat with a level of detail used in the contract

    documents.

    Use the same level of detail the Government would use if it were competing for the

    award.

    Compute the net cost or credit by subtracting the total of the original work from the

    total of the revised work.

    Clearly and adequately describe and identify schedule-related and impact-related

    costs as a separate part of each estimate.

    Prepare the estimate in a timely manner.

    impact cost considerations

    When a modification is directed, settlement includes not only the cost and time change of

    the work directly affected but also the cost and time impact on the unmodified work.

    Generally the contractor first presents impact costs as part of the proposals claimed

    impact costs. The Independent Government Estimator looks for offset ting costs to reduce

    the impact to the Government. The contractor is required to submit documentation to

    support the claimed cost, such as narrative calculations and planned rescheduling. To

    determine the extent of the impact, the approved cost and resource-loaded schedule

    furnished by the contractor must be developed to reflect actual construction as accurately

    as possible. The modification work is superimposed on the original schedule so as to

    section 2.2

    2minimize delay under the given requirements GSA reviews and accepts or requests

  • 7/29/2019 Building Services Project Estimation

    55/92

    minimize delay under the given requirements. GSA reviews and accepts, or requests

    modifications to, the revised schedule.

    The Independent Government Estimator classifies each impact cost claimed as either

    factual or judgmental. Factual costs are fixed and established and can be determined

    directly from records, such as rental or wage rate agreements or purchase documents.

    Once the item has been determined valid as a factual impact, the item cost may be directly

    calculated. The amount of cost change is either stated on the certification document or can

    be determined from the scheduled time change of the construction progress plan.

    Examples of factual impact costs are:

    Escalation of material prices. Escalation of labor wage rates.

    Change in equipment rates.

    Increase for extending the storage period for materials and equipment.

    Increase for extending the contract for labor and subsistence.

    Increase for a longer period of direct onsite overhead personnel, materials, and

    utilities.

    Increase for a longer period of overhead and project office services.

    The Independent Government Estimator identifies judgmental impact costs, which include

    those that are dependent on variable factors such as performance, efficiency, or methodology

    and cannot be stated factually prior to actual accomplishment. The contractors proposal

    must provide clear and credible support for all judgmental impact costs.

    Examples of judgmental impact costs are:

    Change of efficiency resulting from rescheduling. Loss of labor efficiency resulting from longer work hours.

    Loss of efficiency caused by disruption of existing orderly processes and

    procedures.

    Loss of efficiency during rescheduling of manpower.

    Inefficiency incurred from resubmittal of shop drawings, sample materials, etc.

  • 7/29/2019 Building Services Project Estimation

    56/92

    The Independent Government Estimator weighs any premium costs allowed in the base

    contract change proposal against any additional impact costs requested. For example, the

    Mechanical Contractors Associations productivity rates can be higher than those used in

    competitively bid work. The estimator must avoid including the contractors questionable

    impact costs in the initial Government estimate unless each has been deemed justifiable.

    Any offsets to impact costs from deleted work may increase the contractors efficiency and

    productivity, resulting in a credit to GSA.

    estimators support during negotiations

    After the IGE for the modification has been completed, approved, and delivered to the

    Contracting Officer, the Independent Government Estimator continues to support the

    negotiations, as directed by the negotiator. The estimator must become thoroughly

    familiar with negotiating requirements and techniques before participating as part of a

    negotiating team. He or she marks all estimates FOR OFFICIAL USE ONLY to preserve

    balance during negotiations. The overall amount must not be disclosed under any circum-

    stances prior to award.

    13 value-engineering change proposals (VECPs)

    VECPs may require preparation of an IGE. Since a VECP will be supported by contractor pricing,the estimator prepares the IGE in a manner similar to that defined previously in Construction

    Modifications and Claims Analysissection (in Chapter 2.2).

    14 risk management

    The Independent Government Estimator assists in identifying and measuring risks, and then

    in developing, selecting, implementing, and managing options for addressing those risks. The

    several types of risk to be considered as part of a risk-management methodology include:

    15 occupancy agreements and tenant-improvements pricing

    Cost elements are organized in accordance with GSAs pricing policy, which requires a separate

    tenant-improvement estimate for each tenant.

    The agency housing plan and the supporting floor plans must be used to organize the estimate

    detail by:

    Warm-lit shell

    Tenant agency fitout

    Security upgrades

    In addition to the ECCA the estimator must, for each tenant agency, add the GSA-related cost

    elements identified in the Space Planning section of the GSA Pricing Desk Guide, (Section

    3.2.10, page 19) and in the Pricing Implementation for Project Managers Guide, Chapter II

    size of project.

    matrix rows

    The matrix rows are organized by the five distinct stages of any project Planning, Design,

    Construction Procurement, Construction, and Construction Closeout. Within these are

    discrete phases, and within each phase there are several activities. To perform the activities,

    several tasks have to be completed, all as shown on the matrices that follows.

    Planning Stage: The planning stage has four phases:

    1 Preliminary project development

    2 Feasibility study

    3 Program development study (PDS)

    4 Design-build RFP

    5 Baselining

    Design Stage: The Design stage has three phases:

    1 Concept

    2 Design development

    3 Construction documents

    Construction Procurement Stage: There is only one phase and one activity, but two tasks

    are identified.

    Construction Stage: There is only one phase here, but its two main activities are:

    1 Construction modifications and claims analysis

    2 Value Engineering Change Proposal (VECP)

    Construction Closeout Stage: Closeout is the only phase and activity in the Construction

    Closeout Stage.
